HDMI IP - YCrCb 4:2:2 pixels mapping + color depth indication

Hi amildm,

Apologize for the delayed response.

>As for the YCrCb 4:2:2 video format, what's mapping of the pixels on the port vid_data of the HDMI IP (two pixels per clock config)?

>As for 10-bits color depth format, how can I receive this indication from the HDMI IP? What indication about the

>pixel color depth does the HDMI IP provide?

For YCbCr 4:2:2 input format , you may refer to Chapter 5.1.2. Source Video Resampler of the HDMI Intel® FPGA IP User Guide that shows a diagram on how the pixel data is mapped.

Below picture shows the YCbCr 4:2:2 color space pixel bit-field mappings per symbol, this is an example for YCbCr422 is transmitted using 24bpp (8 bpc) HDMI transport:

For Intel HDMI IP, the most significant bit (MSB) will be fill first with pixel data and the unused Least-significant bit (LSBs) are set to zero. The placement of Y and Cb/Cr data is as shown in above figure. For 10bpc case, the placement of Y and Cb/Cr will be the same.

Thank you for your patience.
